Answer:
1. Magnesium and oxygen atoms bond to form an ionic compound; this is evident because one forms a cation and the other an anion. When an ionic compound is formed, one atom "steals" an electron (or electrons) from another. In this case, an oxygen atom (which is pretty electronegative by the way) "steals" 2 electrons from a magnesium atom. The resulting oxygen anion and magnesium cation attract one another to form a bond (more specifically, an ionic one).
2. The oxygen atom needed two sodium atoms to bond because it needs two additional electrons to achieve a stable octet of electrons. 1 sodium atom provides 1 additional electron after it is "stolen" by oxygen, so 2 sodium atoms are needed in total to form the bond.
3. The magnesium atom needed two fluorine atoms to bond because it needs to lose two electrons to achieve a stable configuration/octet of electrons. 1 fluorine atom "steals" one electron, so 2 are needed in total.
Happy Holidays!
Explanation:
It’s an important question because the road to a successful career in science – as with technology, engineering and mathematics, the other STEM fields – can be challenging, often requiring a Ph.D. or other postgraduate training. And once in their fields, there can be political and economic pressures with which to contend. The Bureau of Labor Statistics projects workforce shortfalls for many science fields, though the projected needs differ across the life, physical and natural sciences.
The energy release from sequential redox reactions provides energy to cells most directly by Using that energy to pump protons.
- By transferring electrons during chemical reactions, catabolic pathways break down organic molecules, generating energy that is then used to produce ATP.
- In an oxidation-reduction (redox) reaction, the process of losing electrons (making a chemical more positive) is referred to as oxidation, while the process of gaining electrons (making a substance more negative) is referred to as reduction.
- The inner mitochondrial membrane's electron transport chain receives electrons from NADH and FADH2, which causes an H+ accumulation in the inner membrane space.
- The direct energy source for ATP synthesis is this proton gradient (gradient of H+) flowing via the membrane enzyme complex ATP synthetase.
